摘    要:利用长江口吴淞、高桥、堡镇和芦潮港等代表站近年观测资料,通过单因子线性回归方法,分析平均潮位与平均半潮面的关系.结果表明,各代表站的平均潮位与平均半潮面之间存在着非常好的线性相关关系.根据此关系,利用高低潮位资料即可间接求出平均潮位.由于某一海域的海平面是通过该海域代表潮位站某一时段整点潮位的平均值来获得的,在缺乏长系列整点潮位资料的情况下,可间接地计算出平均潮位,从而为海平面的计算提供了一种有效的方法.

关 键 词:长江口  平均潮位  平均半潮面

Abstract:Using the observational data of Wusong, Gaoqiao, Puzhen, and Luchaogang tidal stations of the Yangtze River estuary in recent years, and by the method of single factor linear regression, the relationships between the mean tidal level and the mean half-tide level were analyzed. The results showed that all stations have very good linear relationship between these levels. Based on this relationship, the mean tidal level can be calculated by using the high and low tide data. As the sea level of certain sea area is calculated using its representative station average of the whole point tide level in certain time, in case of the lack of long series of tidal data, the method here can help us to calculate the mean tidal level indirectly, and further to calculate the sea levels effectively.
